Assignment-1
a.
Managers want to know by next week whether deployment will take place.
Therefore, analysts meet to discuss how useful and accurate their model is.
Answer: Evaluation Phase Explanation – a. One or more models have been produced during the modeling step. Before
we utilize these models in the field, their efficacy and quality must be
assessed. b. Ascertain if the model actually accomplishes the goals that were
established for it during Phase 1. c. Determine whether a significant aspect of the study or business problem
has not received enough attention. d. At last, make a choice about how to apply the data mining findings.
b. The data mining project manager meets with the data warehousing
manager to discuss how the data will be collected. Answer: Data Understanding Phase
a Explanation – a. Gather the data first. b. After that, acquaint yourself with the data and draw some first conclusions
by doing exploratory data analysis. c. Assess the data's quality. d. Lastly, if wanted, choose intriguing subsets that might have useful patterns
in them.

.
Answer: Modeling Phase Explanation – a. Choose and use the right modeling strategies.
b. Adjust model parameters to maximize outcomes. c. It's common to use multiple approaches to solve a single data mining
challenge. d. It could be necessary to go back and revisit the data preparation stage in
order to adjust the data's format to meet the demands of a certain data mining
method. e. The analysts meet to discuss whether the neural network or decision tree
models should be applied
. Answer: Modeling Phase
Explanation – a. Select and apply appropriate modeling techniques. b. Calibrate model settings to optimize results. c. Often, several different techniques may be applied for the same data
mining problem. d. May require looping back to data preparation phase, in order to bring the
form of the data into line with the specific requirements of a particular data
mining technique.
